To all whom it may concern:

Be it known that I, SVEN FJEROH, subject of the'King of Denmark,residing at Grejsdal pr. Vejle, Denmark, have invented cer tain new anduseful Improvements inStay- Rope Tighteners with Turnbuckles Therefor,of which the following is a specification.

The present invention relates to a stayrope tightener together with aturnbuckle therefor. i

Hitherto stay-ropes for electric poles, and the like were generallytightened by aid'of turnbuckles inserted into the said ropes, and havingat their ends eye-bolts with rightand left hand threads.

This method of tightening stay-ropes, however, has. the disadvantage Ithat. the threaded eye-bolts have to bear the tension in the stay-ropepermanently. Further: more the threads are subject to rust and thereby,in case of emergency, render the turning of the screw diflicult or evenimpos sible.

It is the object of the present invention, on the one hand, to avoidthese drawbacks, and, on the other 'hand,to render the construction ofsuch stay-ropes cheaper, by obviating-the necessity of having atightening device in each single stay-rope.-

The stay-rope tightener according to the present invention ischaracterized essentially by two hooked members which may be coupled bythe aid of a perforated link in such positions, that the desiredtightness will be obtained.

Such tightening is preferably performed by means of a special appliance,a turnbuckle.

In the accompanying drawing a constructional form of the presentinvention is shown by way of example. In this drawing 7 Fig. 1 shows infront view the tightener, hooked into the outermost holes of thecoupling link.

Fig. 2 is the same in side elevation, together with the turnbuckleengaged in the hooked members.

According to this drawing the stay-rope 1 is, at a suitable place,interrupted for a certain distance. To each of the ends of the rope isattached a hooked member 2 and 3, respectively, which are coupled toeach other by means of a perforated link 4.

The tightener thus described is employed in such, a manner that thehooked members 2, '3 are engaged in such holes in thecoupling link 1,that thestayrope will have the v 4 propertightnessv t For thus engagingthe hooked members 2 and 3, preferably. a specialturnbuckle, see

Fig. 2, is employed, which acts on: quite the same principle as thoseheretofore, known, g

Y Thisturnbuckle is of thatkind whichconsists of a screw spindle havingrightiand left-hand threads at its ends, on eachof which threaded endsis fitted a nut withla' hook attached to it.

According to the invention not turn relatively to each ether when thescrew-spindle is turned; 7 I

This is renderedpossible, inz'aspecial conthese nuts can structionalformthereof, by the nuts being positively guided by the hooksattachedlto them' travelling to and fro in slots in a guidebar. I if IAs said'before, the screw-spindle of the turnbuckle has atits one end aright-hand thread and at ,its other/end; a left-hand thread. On thethreads of-the spindle 5 screwed the nuts 6 and 7'with the hooks and 9,respectively. I

Thespindle 5may be turned by meansof 1 a swivel-lever 10, and duringsuchturning movement the hooks Sand 9 are guided slots in' a guide-barll.W1 1. 5 I

This guide-bar 11 is rovided with an arm 12, rigidly attached tereto,yby means of which the turnbuckle can be held while itsscrew-spindle is being turned.

The turnbuckle described is employed in the following manner: The hooks8 and 9 are engaged in eyes 13, 14;, respectively, in the hooked members2 and 3, whereupon the coupling-link 4: is put out of tension by turningthe spindle 5 by means of the lever The turnbuckle may also be employedfor disengaging the coupling between the hooked members 2 and 3 as,owing to the hooks 8, 9 having a special shape with a nose 15, it isimpossible to remove the coupling link without its being put out oftension.

The said couplinglink a may be made of various lengths, so thatfwhen thestay-rope is tightened the first time, a long coupling link is employedhavinga suitable number of holes so that it may be used for as manyeye'at one end and'a hook at the other end;

and a coupling link provided with a plural ity of perforations adaptedto engage the hooked members at suitable perforations.-

A stay-rope tightener comprising 'a pair of hooked members each havingan elongated eye-shaped hole at one end, and a hook at the other end;and a coupling link providedwith a plurality of perforations adapted toengage the hooked members at suitable perforations, said hooked membersbeing adapted by means of said eye-shaped holes to be drawn toward eachother sothat said hooks will engage other perforations of Y the couplinglink.

'3. In combination witha stay-rope tightener consisting of two hookedmembers attached to the ends of the stay-rope and a coupling-link havinga plurality of holes, in

which said hooked members engage, a turnbuckle consisting of ascrew-spindle with, at its ends, right and left-hand threads,respectively, nuts screwed on said threads,

' said nuts having hooks adapted to engage'in coupling-link having asaid hooked members of the tightener.

4. In combination with a stay-rope tightener consisting of two hookedmembers at tached to the ends of the stay-rope and a lurality of holes,in which said hooked mem bers engage, a turnbuckle consisting of ascrewspindle with, at its'ends, rightand left-hand threads, re-

spectively, nuts screwed on said threads, said nuts having hooks adaptedto engage in said hooked members of the tightener, a guide-bar havingslots, said hooks moving in said slots of the guide bar.

5. In combination with a stay-rope tightener consisting of two hookedmembers attached to the ends of the stay-rope and a coupling-link havinga plurality of holes, in which said hooked members engage, a turnbuckleconsisting of a screw-spindle with, at its ends, rightand left-handthreads, respectively, nuts screwed-on said threads, said nuts havinghooks adapted to-engage in said hooked members of the tighten-er, aguidebar having slots, said hooks moving in said slots of the guide-barand a handle rigidly attached to said guide-bar.

6. A turnbuckle comprising a screwthreaded spindle; a pair of hookednuts on said spindle; a guide bar secured at each end to said spindle,and having an arm intermediate: of its ends, said guide bar beingadapted to prevent said nuts from rotating with said spindle; and meanscomprising a lever for rotating said spindle.

7. A turnbuckle comprising a screwthreaded spindle; a pair of hookednutson said spindle; -a guide bar for said nuts se cured at each end tothe respective ends of said spindle, and having an arm integral with andintermediate of the ends of said bar; and a lever on the end of saidspindle for rotating said spindle relative to said nuts. p I

8. Incombination with a stay-rope tightener having hooked members and aconnecting link; 'a turnbuckle comprising a screwthreaded spindle, nutson said spindle adapted to cooperate with said hooked member, a guidebar and arm for said nuts secured to said spindle, and a lever forsaidspindle.

In testimony whereof I afiix my signature.
